L4T R32.2.0 has published on July 19th, 2019. https://devtalk.nvidia.com/default/topic/1057580/jetson-nano/jetpack-4-2-1-l4t-r32-2-release-for-jetson-nano-jetson-tx1-tx2-and-jetson-agx-xavier/2 According to #4(thanks to @ADV-LUT), the current script does not correspond to R32.2.0.

It seems like the new version of L4T, R32.2 uses a new dts.

I've used dd to replace the required partitions and move back and forth between standard and spi-enabled system. basically, just used the 5 partitions that change: p3, p4, p5, p9 and p10. would it be possible to set this up such that we can just run a script using pre-built partition images straight from the device itself? thanks
